Abacus: What's That?

Just read this morning in Hindustan Times that more and more Indians are getting drawn to Sanskrit plainly for the sake of learning and using that ancient and almost dead language. There is also a revival of interest in Ayurvedic medicines in India, Yoga has been reinvented and patented and is thriving in the galis of Kailash Colony in Delhi as much as in Hounsolow probably. Vedic Maths and Vedic Astrology are increasingly becoming popular and Management gurus of Indian origin are increasingly looking towards ancient Indian text to come up with new ideas on corporate strategy [Gita is very popular among these gents].
This phenomenon of "going back to the roots" is otherwise known as revivalism and is not always and not necessarily good for the society. Fascism was one revivalist movement in Europe on perceived roots and pasts and has since the 1930s emerged in many forms across the globe.
But the aim of this post is not to start a learned discussion on revivalism but to mention the revival of another "scientific" learning tool which is gaining grounds in India now. The most interesting thing about this learning tool is that it has its origin in ancient Greece and not ancient India.
The "thing" is the revival of abacus the crude but very effective calculator. Many of us would remember the ubiquitous slate boards from our childhood days.These were actually made of slate and not wood and had on the side rows of colourful beads strug together with thin wires embedded in the wooden frame of the slate. Although we were told that these were called abacuses, we really did not know what they were and what functions they served. I came to know much later in life that they were ancient calculators used by the Greeks.
However, recently, I got to know more about them through my daughter who attends a "abacus class" in Delhi and had recently won an interstate trophy in the under six age category. I liked my winning daughter but could not actually figure out how the bloody thing worked. What amazed me was that the thing actually worked and my daughter could do all her additions and substractions correctly using the bleeding and beady instrument [kids use a smaller, handier plastic version of it]. IN fact, she helpfully told me that since the last semester, she has discontinued the use of the actual instument and only uses it "mentally", i.e., in her mind. I have not yet learned the use of the instrument having sat with a few times. I guess I was taught maths by another school of thought, the finger line calculation school. But I must admit, Abacus works and the great art of using abacus is being taught in literally hundreds of learning centres in India. It does not matter if it is of Greek origin, it is helping us continue with our glorious tradition in mathematics. Aryabhatta would have been happy:)
